leekt (taek) submitted a companion EIP to EIP-8141 adding a bounded `AUTHENTICATOR` signature scheme: arbitrary cryptography is executed by protocol in a state-independent, gas-fixed context, while account authorization stays in the ordinary `VERIFY` frame. jochem-brouwer proposed adding an EIP Coordinator role to EIP-5069. forshtat resubmitted the contract storage layout descriptor format as an EIP instead of an ERC. The EF again reminded L1 contract maintainers to check repricing impact. Barnabé wrote about fast Ethereum. P2P networking #7 was held in the evening.

A custom signature path for 8141

New EIP: Frame authenticator signatures

(leekt), submitted, with a Magicians thread at 15:52; this is EIP-8397. A frame transaction can carry a custom authentication proof whose expensive cryptographic verification the protocol executes in a bounded, state-independent context; the signature object is `[scheme, signer, msg, signature]` with `scheme = AUTHENTICATOR (0x03)` and `signer` as the authenticator address. Each authentication is bounded by a fixed `AUTHENTICATOR_GAS_LIMIT`, with no per-transaction or per-key budget.
